Acceptability and validity of the M-ACE for older New Zealanders

A 2020/2021 Summer Studentship research project

Student: Karen Angelita Suresh
Supervisors: Matthew Croucher, Dr Susan Gee
Sponsor: Alzheimers New Zealand Charitable Trust & Health of Older People Service Level Alliance

Introduction

The Montreal Cognitive Assessment™ (MoCA) is the recommended cognitive screening tool for General Practice in New Zealand, however all users will soon be required to pay for certification. In response, a national working group has recommended the adoption of the Mini-Addenbrooke’s Cognitive Examination (M-ACE). The available research suggests that the sensitivity of the M-ACE for dementia is comparable to the MoCA, however, there is no formal research into the M-ACE in New Zealand. Previous international studies were all based in research or specialist clinics.

Aim

The present study therefore aims to assess the acceptability and concurrent validity of the M-ACE in New Zealand primary care, providing useful evidence to inform the move to a new measure. Collaborative parallel studies will target other samples of older New Zealanders with the data being able to be combined across samples.

Method

To assess the acceptability and concurrent validity of the M-ACE, 50 general practice patients will complete both the M-ACE and the MoCA. The order of the tests will be counterbalanced. The amount of time needed to complete the tests will be recorded, and the patients will complete a questionnaire about the relative acceptability of the measures. The acceptability analysis will include statistically comparing the completion time and acceptability of the measures. Concurrent validity will be assessed by the correlation between the M-ACE and the MoCA.

Student researcher’s component of the study

The student will conduct the cognitive testing and be involved in analysis.
